It would have been impossible to disregard the wishes of those, who in the last resort were masters, for a vigorous attempt on Richmond, and the continually unsuccessful attempts that were made did serve a military purpose, for they kept up a constant drain upon the resources of the South. In any well-thought-out policy the objects both of Scott’s plan and of the popular plan would have been borne in mind. That no such policy was consistently followed from the first was partly a result of the long-continued difficulty in finding any younger man who could adequately take the place of Scott; it was not for a want of clear ideas, right or wrong, on Lincoln’s part.
Only two days after the battle of Bull Run, he put on paper his own view as to the future employment of the three armies. He thought that one should “threaten” Richmond; that one should move from Cincinnati, in Ohio, by a pass called Cumberland Gap in Kentucky, upon Knoxville in Eastern Tennessee; and that the third, using Cairo on the Mississippi as its base, should advance upon Memphis, some 120 miles further south on that river. Apparently he did not at first wish to commit the army of the Potomac very deeply in its advance on Richmond, and he certainly wished throughout that it should cover Washington against any possible attack.
